Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 172/971,309/730
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 172,309
Greatest Common Factor of Numerators i.e. GCF of 172,309 is 1 .
LCM of Denominators means LCM of 971,730 as per the given fractions.
LCM of 971,730 is 708830 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 172,309
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 172
List of positive integer factors of 172 that divides 172 without a remainder.
1,2,4,43,86,172
Factors of 309
List of positive integer factors of 309 that divides 309 without a remainder.
1,3,103,309
Greatest Common Factor
We found the factors 172,309 . The biggest common factor number is the GCF number.
So the greatest common factor 172,309 is 1.
Lets's calculate LCM of 971,730
Given numbers has no common factors except 1. So, there LCM is their product i.e 708830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/708830
Therefore, the GCF of Fractions 172/971,309/730 is 1/708830
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 971,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(971,730) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(971,730) x common factors =1 x 1 = 1
LCM(971,730) = ( 971 × 730 ) / 1
LCM(971,730) = 708830 / 1
LCM(971,730) = 708830
